1 Claim.

This invention relates to a window sash holder, more particularly to a sash holder for windows of the easement type.

The primary object of the invention is to pro- 5 vide means for securely holding a hinged window or the like open to any extent desired, which extent of opening may be freely varied at will.

A further object of the invention is to provide a holder of the character aforesaid which may be 10 economically stamped from metal or any other suitable material, and which may be readily applied to installed windows without any alterations in the existing structure thereof.

An embodiment of the invention is illustrated 16 in the accompanying drawing in which- 55 equal to the width of the recess II.

Figure 1 is a front elevation of a Window showing the invention in association therewith,

Figure 2 is a side elevation of the structure shown in Figure l, with a dotted line showing of the sash held partially open,

Figure 3 is an enlarged elevation of the elements forming the holder `in assembled relation,

Figure 4 is an elevation of the assembled elements of the holder as viewed from the left of 25 Figure 3,

Figure 5 is a section taken on the line indicated 5 5, Figure 4,

Figure 6 is a detail in elevation of one of the clamping elements of the holder, and

Figure '7 is a horizontal sectional View of a modied form.

Referring to the drawing in detail, the numeral I indicates a window frame having a sash 2 hinged thereto at the top of the sash. While the 35 window and sash herein shown are of the type commonly used in basements and attics, the holder may be applied with equal facility to a sash which is hinged at one side or at the bottom.

Fixedly. secured to the frame I by suitable 40 holdfast devices, such as'the screws 3 is the base 50 9 is provided at one side with a flange Ill inturned in spaced relation to the body of the clamp to provide a recess II adapted to receive a side portion of the bar 6 therein. At the opposite edge of the member 9 is a flange I2 of a thickness Intermediate the flange I2 and recess I I, the member 9 is provided with a polygonal opening I3.

When the parts are assembled a polygonal prtion I4 of a bolt indicated generally at l5 eX- tends through the opening I3 in engagement with the walls thereof and in engagement with one edge face of the bar 6, the opposite edge of the bar being disposed within the recess II. Lying flat against the ange I2 and bar 6, and interposed between the iiange and bar and the leg 8 of the bracket l, is a washer I6 which seats on the bar 6 and flange I2. The bolt vI5 extends through washer and through an opening I'I in the leg 8 and is provided at its projected end with a wing nut I8. The inner edge of washer I6 and the opening I'I align with the opening I3.

When the holder is assembled in connection with a sash and frame, and it is desired to adjustably open the sash, the nut I8 is loosened to permit sliding movementof the bar with respect to the clamping member 9, washer I6 and leg 8 of the bracket l. Upon manually moving the sash about its hinged connection, the bar 6 swings about its pivotal connection with the arm of the bracket 4, and also slides with respect to the bracket and clamp assembly secured to the sash. When the nut I8 is tightened the bar 6 is iirmly clamped between the member 9 and washer I6 with the polygonal portion I4 of the bolt engaging the walls of the opening I3 and also engaging one edge face of the bar 6, the opposite edge of the bar being engaged by the wall of the recess II. Thus it will be seen that when the nut I8 is tightened, both sliding and turning movement of the bar 6 is prevented.

With reference to the modification shown in Figure 7, the clamping member of the holder is indicated at I9 and it is formed with inclined side flanges 20, 2|. The bar 6 extends through the member I9. The ange 20 opposes a side edge of bar 6. The member I 9 has an opening 22 for the passage of bolt I5 which carries nut I8. The bolt I5 also extends through the leg 8 of the bracket 1. Interposed between said portion 8 and bar 6 is a cup-shaped Washer 23 which not only seats on bar 6 but also on flange 22.

Although but one washer I6 is shown, it is to be understood that two or more may be employed. The washers I6 and 23 constitute spacers and are used to obtain the space needed between frame of window and sash and also to clear the square on the bolt as the nut will not go down that far. Owing to the arrangement of either of the spacer Washers with respect to the bar 6 and a clamp the canting of the latter and the bar 6, as well as the twisting of the latter is prevented when the nut is screwed home.

It is to be understood that the above description and referred to illustration of the invention represent a practical and preferred embodiment of the same, and that changes in the details of construction may be resorted to so long as such changes fall within the scope of the invention as dened in the appended claim.

What I claim is:-

In a holder for adjustably holding open a hinged window sash with respect to a Window frame, said holder comprising a bracket adapted to have its base anchored to the frame and including an arm extended from said base, a bracket adapted to have its base anchored to the sash and including a leg extended from the base, a clamping element provided with side flanges and opposing one face of and disposed lengthwise with respect to said leg", a bar pvoted at one end of said arm, extending between said leg and element, seated on the latter and arranged in close proximity to one and spaced from the other of said flanges, a spacer member for said element bearing respectively against the said face of said leg, one face of said bar and the said other of said flanges, a bolt extending through said leg, element and member and positioned between said bar and the said other of said flanges, and a clamping nut coasting with the boltfor clamping said bar, element and member stationary to said leg When positioned at a selected point of said bar, said element and bolt having coacting means to prevent the turning of the bolt relative to said element, leg and member, the coacting means on said bolt bearing yagainst a side edge of said bar.
